How to Update Catalog Task Variable using REST API

[rakshith_shetty]

I am trying to update a sc task variable using patch api (/api/now/table/sc_task/<task_sys_id>)

Body-

{  

   "number": "SCTASK1502273",  

 "variables.risk_change1": "No",    

"variables.risk_assessment": "tEST ",    

  "work_notes": " testing"

 }

fields are updating but sc task variables are not getting updated.

Want to know like what is process for updating the variables using REST API.

can someone assist me ?

I've never done that myself, but I am sure that you could achieve that with scripted REST APIs. The simple reason is that the variables on a SCTASK record are saved in another table - sc_item_variables_task. That is only the connection, no value there.

Because these variables are not actually connected directly with SCTASK, as they come from parent RITM, you also have to query sc_item_option_mtom to get/update the variable value.
